I have no connection with these people but I thought I'd share this. When I was driving school bus I had acres of glass to keep clean and I used one of these microfiber cloths. If you have never tried one you won't believe how they work. You can throw the Windex away because you only need water. They clean and leave absolutely no streaks, you just rinse them out and wring them out and wipe the windows and they last a long long time. They are amazing. Sorry if I sound like an infomercial but really they are magic. It is so nice not buying paper towels and glass cleaner. ;)
